As a home gardening enthusiast, growing orchids is a popular choice for many. However, for orchids to thrive, proper fertilization is essential in addition to providing ample sunlight and water. But what should we pay attention to during the fertilization process? Let's discuss a guide to orchid fertilization.
Choosing Fertilizer
When choosing fertilizer for orchids, pay attention to its type and composition. Orchids are acid-loving plants, so choosing acidic fertilizer is more suitable for their growth needs. Moreover, it is best to choose fertilizer specifically formulated for orchids.
Chemical Fertilizer and Organic Fertilizer
For fertilization, we can choose between chemical and organic fertilizers. Chemical fertilizers are relatively easy to obtain, but overusing them can have adverse effects on orchids. Furthermore, long-term use of chemical fertilizers can lead to soil acidification. We should be cautious when using chemical fertilizers. Organic fertilizers, on the other hand, are gentle and will not harm the plants when applied.
Timing of Fertilization
During the growth process, orchids require different fertilizers at different stages. During the active growth period, we should apply more fertilizer. At the same time, autumn and spring are also good times for fertilization. Also, fertilization should not be too frequent during the growing period; attention should be paid to the amount.
Timing of Watering and Fertilizing
When watering and fertilizing, we should pay attention to the time interval between them. After watering, you should wait for a period before applying fertilizer. Otherwise, the fertilizer will be washed away with the water, leading to poor effectiveness. Wait 1-2 days after watering before fertilizing.
Methods of Fertilization
During fertilization, we can use root-zone fertilization or foliar spraying. Root-zone fertilization means sprinkling the fertilizer on the soil surface and then mixing it in gently. Foliar spraying, on the other hand, involves spraying diluted fertilizer directly onto the orchid leaves. However, when using foliar spraying, the concentration should be controlled.
Amount of Fertilizer
When using fertilizer, we should control the amount based on the orchid's growth needs and the fertilizer's concentration. Usually, fertilizing once every 7-10 days is sufficient. Moreover, the amount of fertilizer should be gradually increased to avoid over-fertilization.
Fertilizer Concentration
When using fertilizer, we should control its concentration. Using fertilizer that is too concentrated can have adverse effects on the orchid's growth. It should be diluted according to the ratio on the instructions when applied.
Fertilization Method
When applying fertilizer, we should pay attention to the method. If we use water that is too warm to dilute the fertilizer, it will be detrimental to the orchid. When using fertilizer, use tap water or cooled boiled water for dilution.
Fertilization Frequency
When applying fertilizer, we should pay attention to the frequency. Applying fertilizer too frequently can harm the orchid. There should be an interval of time between each application of fertilizer.
Fertilizer Composition
When choosing fertilizer, we should understand its composition. If the chosen fertilizer contains too much nitrogen, phosphorus, and other elements, it will have a negative impact on the orchid's growth. Pay attention to its composition when selecting fertilizer.
Plant Condition
Before applying fertilizer, we should observe the plant's condition. If the plant is growing poorly, it may be due to over-fertilization. The plant's condition should be observed before applying fertilizer.
Soil pH
When using fertilizer, we should be aware of the soil's pH level. If the soil is too acidic, some alkaline fertilizer should be chosen. In contrast, if the soil is slightly alkaline, some acidic fertilizer should be chosen.
Drainage
When applying fertilizer, we should pay attention to the drainage. If the soil drainage is poor, it will lead to root damage, which in turn will adversely affect the orchid.
Indoor and Outdoor Orchids
The methods of fertilizing indoor and outdoor orchids are different. During the growth of indoor orchids, we should control the temperature and humidity and use fertilizer suitable for them. During the growth of outdoor orchids, attention should be paid to light and cold protection.
Orchids require proper light, water, and fertilizer to grow. When applying fertilizer, we should choose the right fertilizer and control the timing, frequency, and amount. At the same time, when using fertilizer, attention should also be paid to its concentration, composition, and application method. Only by using fertilizer correctly can orchids thrive.
